    What is dredging?

    Q: What is dredging? A. Dredging is essentially the underwater excavation of a channel. Throughout the year, sediments within the water column will settle and accumulate within the channel, a process that is known as shoaling. The shoaled material is removed to the authorized project depth (plus advance maintenance and allowable overdepth) to allow for safe navigation between dredging cycles, a process known as maintenance dredging.
